SHUTTLE;

Specification of Letters Patent.

Patented Nov'. 25, 1913.

Application' filed February 2s, 1912. seriaiiwesaiis.

To all whom if may concern:

Be it known that we, JEAN BAPTISTE DAUDELIN and EUSEBEV H. DAUDELIN, citizens of the United States, residing at Fall River, county of Bristol, Commonwealtlii of Massachusetts, have invented certain new and useful Improvements in Shuttles, of?

which the following is a specification.`

Our present invention -relates :t-o. certain improvements `in hand threadingshnttles, with particular regard to the checking of any possible escape of a thread froman eye during the run of the shuttle. Heretofore in this art, even the most'perfectthreading eyes and threading slots haveat times failed to hold the thread under the constant` writhing and twisting which occursin vthe ,unspooling of the thread from the bobbin.:

It is, therefore, the object of our presentinvention to provide a simple means for preventing the escape of the thread-from an eye by which any thread securing device may be rendered more effective and which also makes it possible to construct thread guards and threading eyes with less minuteness of detail and less care, thus reducing the cost of production.

@ur invention consists, broadly, in the introduction of a member composed of inaterial in which flexible members are presented with their free ends projecting inwardly toward the threading eye and across the path of entry to that eye so that while a thread may crowd by it in entering it will beco-me entangled with the free ends in any attempt to ret-urn.

As illustrative of our invention, we have shown in the accompanying drawings a form of device which we find well adapted to practical use. This form we shall describe as disclosing the principles of our invention and its adaptation to shuttles.

Throughout specification and drawings like reference numerals are employed to indicate corresponding parts and in the drawings, Figure 1 is a plan view of the delivery end of a shuttle embodying our invention, Fig. 2 is a side view of the same, Fig. 3 is a section on the line 3 3, Fig. 2, Fig. 4 a detail of a threading eye plate removed, Fig. 5 is a plan view of a shuttle fitted with another form of eye plate, and Fig.A 6 a side view of a shuttle end shown in Fig. 5.

The shuttle body indicated at l has the usual chamber in which the loobbin 3 is located from which the thread `2 is to be drawn. In the form shown in Figs. 1 and 2 we provide a plate 4: having a pronged inner end and an outer end formed as a depending and'rearwardly faced hook13, the point l0 of whichis upturned and carried until it overlaps. theedg'e of the plate. This hook defines the delivery eye ll. The upper vsurface of the plate is cleared` away Aat 42 for thefree'passage of the thread and is provided Vwith a forward extension 14 past whichl the threading slot passes before making its backward turn into the threading eyeVV and 6 We have substituted for the hook 13 each other closely but leave a narrow openingthrough which'the thread may rise.

Referrin' again to Figs. 1 and 2, we provide a gbrous member 9, preferably -of cotton or hemp, which is rolled in the form of a cord and drawn in through a vertical hole formed through the upper face of the shuttle. The lower end of the fibrous body is allo-wedto project as a brush between the point 10 andthe opposing shoulder of the hook 13. When, therefore, the thread is drawnv down through the slot 6 and rearwardly through hook 13 it will pass over p the end of the hoo-k into the eye 11, pushing aside the brush-like end of the member 9. Upon attempting to return, however, it will engage the fibers of the brush-like end` of the member 9 and become engaged therethe-modified form shown in Figs. 5:

with, spreading the same so that escape past y the point 10 will be impossible.

In the form shown in Figs. 5 and 6, we have provided a similar fibrous element 91. This we have drawn through from the lower side of the shuttle, allowing its free end to project between the points .101. In threading the shuttle shown in Figs. 5 and 6 the thread 2 is drawn down through the vertical slot 6 in the same way as last described, then rearwardly until it rises between the points 101, 101 and into the space 111 defin-ed by these fingers. In entering the. space 111 it passes the end of the brush 91 in the same way as described in connection with Figs. 1 and 2. In the same manner, if it attempts to escape the thread will come in contact with the brush-like end of the inember 91 and become entangled therewith.

It will be readily apparent to those skilled in thev art that our invention mayv be'rapplied in combinationwith a great variety.

of forms of threading eyes and thread guards.V Y Y Our brous member may be in the form VYof a cylindrical brush or as an elongated strip according to the nature of the pas-V sage which itisintended to close. ./Ve vdo Y' not, therefore, limit our invention to any fio particular.formof member or to any particular material, all such modificationsl be- A ing understood to be within thegsoope of f our invention if within the limitso-f the 'Copiesfoi Ythis patent niay'be obtained'for appended claims; Y H Y i Y What we therefore claim and desire .to Vsecure by Letters Patent is :V

1.In ashuttle having arthreading eye and a threading slot, a guard fitted inrsaidi eye and having a pair of points defining said eyebut'with ay passage between theirends, p andav "fibrous member I rojecting between said points and havingA 'ree ber ends disiposed inwardly therebetween.V y

2. In a shuttle of the class described having a'threading eye and a threading passageV leading into said eye, a thread check composed of longitudinally disposed fibers set in said passage and disposed inwardly along said passage toward said eye and having no exposed fiber ends at its outer part, but having a surface of free liber ends projecting toward said eye and effectivelyv JEAN BAPTISTE DAUDELIN.
